Notes on Power-up
The ADNS-6030 does not perform an internal power
up self-reset; the POWER_UP_RESET register must be
written every time power is applied. The appropriate
sequence is as follows:
1. Apply power
2. Drive NCS high, then low to reset the SPI port
3. Write 0x5a to register 0x3a
4. Wait for t
5. Write 0xFE to register 0x28
6. Read from registers 0x02, 0x03 and 0x04 (or read
During power-up there will be a period of time after the
power supply is high but before any clocks are available.
The table below shows the state of the various pins
during power-up and reset.
Notes on Shutdown and Forced Rest
The ADNS-6030 can be set in Rest mode through the
Configuration_Bits register (0x11). This is to allow for
further power savings in applications where the sensor
does not need to operate all the time.
The ADNS-6030 can be set in Shutdown mode by
writing 0xe7 to register 0x3b. The SPI port should not
be accessed when Shutdown mode is asserted, except
the power-up command (writing 0x5a to register 0x3a).
(Other ICs on the same SPI bus can be accessed, as long
as the sensor’s NCS pin is not asserted.) The table below
shows the state of various pins during shutdown. To
deassert Shutdown mode:
1. Write 0x5a to register 0x3a
2. Wait for t
